Already Installed Bug on New signups.

I have stuff up.

I was trying to be clever and was trying to mass delete 91K Post on blogline_home db trough PHP MyAdmin so i just emptied all the tables oops BAD idea

I then tried to do a restore trough WHM and it crash halved way trough.

SO then i log in to the server with SSH cd /backup and i still had a back up of the blogline_home.sql and blogline_global.sql i then ran

mysql -p -u blogline_wrdp1 blogline_home < blogline_home.sql
mysql -p -u blogline_wrdp1 blogline_global < blogline_global.sql

They restored and all my data were back till a point

Now here is the strange part when i tried to add a new blog i get this below.

Already Installed
You appear to have already installed WordPress. To reinstall please clear your old database tables first.

The strange thing is every thing elce is working 100% oldblogs / domain / multi domains it is just the sign up page that is not working

Ps here is a list of things i have done

/scripts/upcp --force
/scripts/checkperlmodules --force
/etc/rc.d/init.d/postgresql restart
mysqlcheck -u root -pbFtfdmBwIZwT --auto-repair --optimize --all-databases

I have remove all plugs and the mu-plugins and change to 2010 theme and uploaded a fresh copy for wordpress 3.4.1 but still i get this err.

Please try an help me get BlogLines Working
